概括
巴基斯坦的当地气候感知往往与观测到的洪水,温度和降雨趋势保持一致. 然而,干旱时代的感知往往被高估,这凸显了需要更好地沟通气候风险的需要.
科学领域:
- 气候科学是气候科学.
- 社会科学 社会科学 社会科学
- 环境研究是环境研究.
背景情况:
- 牧民和农牧民社区非常容易受到气候变化的影响.
- 了解当地气候感知与观察到的趋势之间的对齐对于有效的适应战略至关重要.
- 在Koh-e-Suleiman山脉等偏远地区的数据稀缺性需要创新的研究方法.
研究的目的:
- 检查当地对气候极端现象的看法与巴基斯坦科赫苏莱曼山脉观测到的气象趋势之间的关系.
- 评估社区对各种气候变量 (包括洪水,降雨,温度和干旱时期) 的感知的准确性.
- 确定影响气候变化认知准确性的社会经济因素.
主要方法:
- 在Koh-e-Suleiman Range的198名受访者收集了家庭感知数据.
- 分析了气候记录 (1980-2022) 并使用巴基斯坦气象局数据计算了29个极端气候指数.
- 采用曼-肯达尔和森的斜率测试来评估趋势,以及准确性测试,偏差分类,回归和机器学习 (CART) 来比较感知与观察.
主要成果:
- 感知与洪水,降雨强度,温度和温暖时期的观察趋势非常相匹配 (准确率≥80%).
- 寒冷时期 (71.7%) 和降雨 (60.6%) 的准确度中等,而干旱时期的感知在很大程度上是不准确的 (75.3%被高估).
- 回归分析将教育,年龄和牲畜所有权与感知准确性联系起来;机器学习揭示了收入,年龄和群体大小对干旱和降雨感知的非线性影响.
结论:
- 当地对气候极端的感知可以成为一个有价值的资源,特别是对于洪水和温度等变量.
- 在干旱的感知中存在显著的差异,这表明需要有针对性的气候风险沟通.
- 将当地知识与观测数据相结合,对于在数据稀缺的牧场地区制定特定环境的气候适应和沟通战略至关重要.

What is Climate?
21.2K
Climate refers to the prevailing weather conditions in a specific area over an extended period. As the saying goes, “Climate is what you expect. Weather is what you get.” Climate is influenced by geographic factors, such as latitude, terrain, and proximity to bodies of water.

Water plays a significant role in the life cycle of plants. However, insufficient or excess of water can be detrimental and pose a serious threat to plants.

Global Climate Change
29.2K
Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.

Responses to Heat and Cold Stress

Every organism has an optimum temperature range within which healthy growth and physiological functioning can occur. At the ends of this range, there will be a minimum and maximum temperature that interrupt biological processes.

Responses to Salt Stress
14.8K
Salt stress—which can be triggered by high salt concentrations in a plant’s environment—can significantly affect plant growth and crop production by influencing photosynthesis and the absorption of water and nutrients.
